' ANTlFRlCTlON- BE-ARING.

To all whom it may concern:

Be it known that I, LOUIS H. Summer, a citizen of the United States ofAmerica, and a resident of East Orange, county of Essex, State of NewJersey, have invented certain ovements in Antifriction-Bearings, of wich the followin is a specification, reference-being had to t eaccomlpanying drawings forming a part thereof.

l\/ y invention relates to anti-friction bearings, and particularly tothat class of anti-f friction bearings known as roller or ball bearings.

' In the ordinary form of roller or ball bearings concentric bearinmembers are provided with" rollers or alls between them, upon which thesaid members roll in their relative rotation. Because all the rollersrevolve in the same direction it follows that the adjacent surfaces ofcontiguous rollers move 7 in opposite directions, and hence that therethereby cramping the parts or seriously af-,

is a rubbing contact resulting in more or less frictionv between thebearing rollers themselves. 1

provide an improved form, construction and arrangement of-be'aring, inwhich separating and it is to this specific class of bearing thatmykpresent invention particularly relates.

1 yinvention also conslsts n an arrangement and constructionof bearingin which provision ismade whereby one bearing memer may tip or cant withrespect to the other-,-

so that the two members may be thrown out of alinement to a certainextent without fecting the eflicient ruiming qualities thereof. In orderthat my invention maybe fully V understood, I will now describe certainembodiments thereof illustrated in the accompanying drawings, and. willthenpoint out the novel features in claims. i I p In the drawings:Figure Us a view'in central vertical longitudinalsection through ananti-friction bearing embodying my inventionQ Figs. 2, 3,4 and 5 aresimilar'views through one set of the said bearings, the relationship andconstruction of parts being.

The shapes and forms oftheparts arevaried throughout, it "being wellaunderstoodthatmy invention is in noway limited-to the precise form and construction of 'the- -parts,1,andit will be also-understood that'the. shaft or axle 3 10 may be astationary or rotative member,

as also may be the hub 11. In other'words the hub-may rotate and theshaft be station- 'a'ry, the shaft may rotate and the'hub be stationary,or both parts may rotate but'at different speeds or indifferentdirections.

' In-Fi 8 I have shown diagrammatically oft the pre erred relationshipof angle of the tracks (either inner or outer), the same beingsubstantially tangent to a circle struck from the center of the bearingas a whole. The result of such an arrangement is that the relativestationary and rotative bearing members may be quite a little outof-line without the arts becoming cram ed, or the efficiency heanti-friction qua lties of the bearing being seriously affected.

It will be readily understood by reference to the diagram of-Fig. 8 thatthe rollers 16 as a whole, the member 12 being u' on-the' practicallyan-inversion of the may move along the faces of the tracks 13 for quite.a little distance in either direction without any seriousdis-arrangement of parts.

Thediagram Fig. 8 may be directly applied to the form. of bearing shownin Fig. 1, the

angle of the'trfacks 13 and their relationship.

Instead of thetracks 13 being straight,

. they maybe curved, as will be well understoodpand the curves thereofare concentrio with the center of the bearing as' a whole,

as shown in the "diagram Fig. 9, the bearing members may be tilted withrespect to each.

other to" any degree permitted by the parts without thereby affectingthe running qualities thereof.
